Ultrahigh frequency radiation characteristic simulation method and system for cable body

The present invention provides a cable body UHF radiation characteristics simulation method and a system, which method comprises the steps of: the cable body and the external space pre-built model is adaptive mesh; partial discharge source is provided in simulations ; providing one or more data collection points; each data collection point was obtained after a preset time acquisition simulation results, the UHF radiation characteristics obtained partial discharge signal cable body according to the results of the collected data collection points. The simulation results of the invention can be a good fit engineering practice, and on-site tests have better economy and enforceability compared.
